The web W is transferred from the wire (5) to a press section with a single dewatering nip (9) formed between an upper shoe press roll and a lower suction roll. A first press felt forms a loop around the shoe press roll (10) and a second press felt forms a loop around the suction roll. Downstream of the single dewatering nip (9), the web W is separated from the second press felt is transferred in an open draw to a drying section (13).
